transfer data between devices

To transfer data between devices, Apple introduced several relevant features and APIs at WWDC 2024. Here are some key points:

1. Transferable API:

   • The Transferable API allows you to describe how your models can be serialized and deserialized for sharing and data transfer. This can be used to convert and export your app entities into various formats like PDF, images, and rich text, making them meaningful to other apps.
   • For example, you can use Transferable to convert an app entity to a PDF and pass it to Mail as an attachment or convert it to an image and import it into the photo library.

2. Accessory Setup Kit:

   • The Accessory Setup Kit streamlines the process of setting up accessories by combining several types of permissions into one out-of-process picker. This includes Bluetooth and Wi-Fi access, making it easier to connect to and manage accessories.
   • This kit simplifies the pairing process, allowing your app to connect to accessories with just one tap, and provides new accessory management tools.

3. Bluetooth and Local Network Access:

   • The updated Bluetooth permission in iOS 18 helps users grant full access only when necessary. This is particularly useful for apps that need to connect to accessories over Bluetooth and Wi-Fi.
   • The Accessory Setup Kit also ensures that your app can connect to paired accessories without requiring full access, enhancing user privacy.
